Today we will be carrying on with some more work on multiplying non-unit fractions. If you need to you can refer back to the slides and video from yesterday, as well as the slides from today.
As always, pick your starting point (based on your work from yesterday) and use the answers to help you decide when to move on.
First, do your Activating Prior Knowledge task:
Today, you need to continue with your writing!
Read through your writing from yesterday then colour-code so far using your Success Criteria - this will show you what you still need to focus on including in the next part of your writing.
Continue your writing, making sure you get all that you need to in (use the example text to help you).
if you finish, colour-code the rest of your work, ready for editing it tomorrow.
I hope you all found some interesting materials last week and have used some new science vocabulary.
This week's science links to a design and technology project later in the term so today's enquiry will be useful.
We are going to investigate the which materials are thermal insulators and which are thermal conductors. You used the terms conductor and insulator when you learnt abut electricity.
Which material will keep food warm the best?
At school we will be using thermometers to measure how warm water stays in containers wrapped in different materials. To do something similar at home without needing a thermometer but still doing some fun science, you will do a slightly different enquiry.
You will need
Glasses of a similar size
A clock/ timer
Different materials to wrap around a glass e.g paper, fabric, tin foil
Ruler with mm
1. One glass will be the control experiment and will have nothing wrapped around it. Put that glass to oneside.
2. Chose a material and wrap it around the glass ( not the bottom or top). If you want to test another material chose another glass and wrap your second material around that. It is up to you how many you do but remember we need to keep the variables the same.
3. Put an ice cube in each glass.
4. Every 15min measure the ice cubes but don't touch them with your hands because you'll melt them!
If nothing is happening every 15 minutes then make the time between measuring longer for all of them. It depend how warm your room is.
5. Record your findings in a table.
6. When the ice has melted stop or when dinner is ready!
Conclusions ( Important y5 science bit)
What did you notice? Did some materials keep the heat out and the cold in ( thermal insulator)? These materials would keep the ice cube from melting. The control ice cube should have melted first because there was no material stopping heat travelling to the ice cube?
Did you keep all the variable the same?
In class we will be investigating electrical conductivity and insulators!
